Jan 08, 2020 Overview of Mac OS X Mountain Lion 10.8 ISO & DMG Image Kernel. A DMG disk image file is Apple's container format for capturing entire drives or disks, similar to ISO for other platforms like Windows. It consists of data blocks that represent a physical disc. If you're on a Windows machine, you're limited in what you can do with DMG files.
Windows and Mac computers use different types of disk image files. In the macOS environment, Apple uses DMG. On the other hand, Windows uses ISO, which is also compatible with the Linux environment. However, ISO is also functional in Mac. Such compatibility makes ISO files, especially for software installation, better than DMG. This means that DMG to ISO conversion is inevitable. The first step in converting DMG to ISO online or offline is understanding both file types. The second is knowing whether to convert DMG to ISO on Mac, Windows or online. All this information is well laid out below.
Part 1. What are DMG and ISO
DMG is the short form for the term Disk Image file. It refers to a file format that creates a mountable disk image that is used in Mac computers. In simpler terms, it is the digital form of the physical disc. The DMG file stores compressed software installing tools for Mac. Therefore, when you download any Mac program online, the file downloaded is likely to be a DMG format. Basically, a program is usually downloaded from a software manufacturer’s site.
Upon mounting the file, the generation of a virtual disk takes place from where you can copy the program to applications or simply run the installation script; choosing between these two options depends on the installation type. A DMG file comprises of a raw block of data that is encrypted in various encryption methods and compressed through multiple compression algorithms as well. If you wish to protect a DMG file, you can always apply a password.
DMG files are usable only on Mac computers and hence not compatible with Windows operating systems. If you would like disk image files in your Windows computer, you must use ISO files, which use the International Organization for Standardization file format. ISO files are perfect at mounting disk image files in any Windows operating system, especially the most recent, Windows 8 and 10.
Some people use them to emulate DVDs, CD or other disk drives virtually. An ISO file also holds the disk images of operating systems such as Linux that you can copy in the USB drive or burn into a disk. It can further send Windows software installation files online. However, a binary package with the MSI installer is used to send the files.
Unlike DMG files, ISO files are compatible with Mac operating systems. On the other hand, the ISO format lacks features like compression algorithms and encryption methods. Since ISO files are compatible with Mac and Windows, it is advisable to turn DMG into ISO.
